Dear all,
As usual we get good explanations from Guru Achalam! Just this small addition may add some flavour. We know that if we want to light a lamp we need a lighted match stick. No amount of trying with a plain stick can help us light the lamp. Exactly like this we need a Sri Guru who has already been intitated and is practicing that mantra to intitiate us. In fact we can read the word intitiate as ingite us! Ignition can happen only from a charged spark plug!
